Mountain Lion UI Lag on rMBP !!! (Let's Make this thread serious and hope for a fix)

will be interesting to find out that the whole issues not with the Graphic card but dodgy SSD!!!

Did you guys installed gfxCardStatus?

I've installed it 1 hour ago and my computer seems back on track and Diablo 3 runs smooth again.

I also suggest you install the latest CUDA drivers from nVidia website...

A lot of people install gfxCardStatus and run a Cinebench, once with the nVidia and once with Intel.

The people having this problem with their graphics have better results with the Intel...!

Yeah it seems that there is a proble with the integrated graphic card Intel. Using just the Intel card causes a lot of lags. But I mean nevertheless this shouldn't happen anyhow. The rMBP is a very strong machine which costs a lot of money. So I can expect that everything should work smooth and proparly. Apple should be able to do that.

****, if it is.. what can we do!?

Suggesting the SSD is a fault sounds bizzare to me. The graphics drivers seem most likely to be a fault (or the graphics switching).

Although they do seem to be improving ever so slightly in each minor version release of Mountain Lion.

As a very simple test I have been using RDM to set my resolution to 1920x1200 (HiDPI) and viewing this website (noticing the animated clouds) and then setting the resolution to 19200x1200 - the none HiDPI one - and viewing the website again. The difference is quite noticable, as well is the performance throughout OSX.

But, of course I haven't paid £2500 for a retina display to run in a lower quality mode, so I end up switching back to HiDPI and suffering the lag.

Im am interested to know if anyone from Apple is reading this thread at all?

So to me but let's see if this resolves our problem.

I am also interested to know whether apple takes care about theese issues?!

I am very disappointed about the fact that apple promises a retina display, btw which is really amazing, but may be the hardware does not fulfill the requirements to run such a resolution of a display properly.

I hope they work on it!

somehow i'm thinking they won't fix it ever 😟 they are thinking that we are fully idiots 😟

They'll have to fix it, i'm experiencing the same lag problems, but i´m on a early 2011 15'' MBP, wich means its a software issue and there are more products affected

That's a new view. I really assumed that the lag is mainly caused by hardware issues. So could you just describe short how you experience the lag? I'm just wondering if it is almost the same as we have on our retina machines. Thanks.

at first, when i installed ML it ran smoothly, but a few week later it became all the features that required animation became slightly slower, such as mission control or launchpad, the issue that bothers me is that when i open safari the computer sometimes won't respond to the gestutures, i can move the cursor, but my mac won't respond until a few seconds later like trying to catch up with the actions i triggered before, generally the lag becomes stronger while using Safari, and i've also experienced the total "block" of my mac when i opened a tab on safari, when the only solution is to reboot it manually, it has happened to me 5 times in the past three weeks, and is really anoying, i had never experienced such problems before neither on lion nor snow leopard.

Has somebody made the last update (well its not a proper update, it fixes chinese on Mail app and who knows what else) but I think my computer less laggier now??

I did ! But absolutely no change for me !

They're too busy fixing their !@#% maps.

We'll be lucky to see a fix in 2012.

Yeah, there really seems to be something wrong with integrated graphics drivers, or the way the graphics are switched. I'm on all the latest updates, and if I force it to use the GPU graphics, all animations are perfectly smooth. On the Intel chip, they are horribly laggy. Pretty shoddy for such an expensive machine.

This thread can't ever be a serious thread if people keep posting things that make no sense.

Firstly, Every Macbook Pro Retina I tested in the Mac Store has UI Lag. If YOU cannot detect the UI Lag, than your threshold for detecting it is higher then the rest of us or you simply don't know what UI lag is. I can't speak for every person who has MBPr, but if every single one in the Mac Store has UI Lag, then why would only certain peoples computers NOT have UI Lag?

Secondly, the display type and or SSD is not causing your UI Lag. This is 100 percent not true.

Thirdly, doing fresh installs, or updating the OS does NOT solve the problem. It never did, so when you come into the thread and say that the lag was better for a little while when you updated your OS, but then got worse again, you are misleading people into thinking that updating the OS or doing a fresh install will fix the UI Lag. If the lag "came back" for you, it was never gone and always there in the first place BECAUSE...

The UI Lag has to do with the GPU's onboard the MBPr. That is what is causing UI Lag. If you switch to your nvidia GPU, you will notice less lag because the problem has to do with refershing the insane amount of pixels on the retina screen.

What we need is a statement from apple saying, "we acknowledge the UI Lag, it is because of a driver issue bla bla bla" OR "we acknowldge the UI Lag, sorry we sould you hardware that doesn't fully support the retina screen yet"
